Active clinical trials for "Frailty"

This trial will take the form of a feasibility study; designed to assess the feasibility of a proposed future clinical trial in this setting. This proposed future clinical trial is proposed to assess the impact of physical activity, in the form of specialised chair based physical activity intervention, on the physiological, psychological, cognitive, social and emotional health, and functional capacity of geriatric populations with pre-existing frailty within a residential care setting; recognising health as a holistic concept incorporating a multitude of inter-related dimensions. This feasibility study is single-centre (taking place at the Olivet Christadelphian care home, 17 Sherbourne Road, Acocks Green, Birmingham, United Kingdom ).

Frailty is a syndrome characterized by decreased reserve and diminished resistance to stressors. The proposed research will evaluate the association of frailty with chronic kidney disease (CKD). The prevalence of frailty increases with age and with CKD, but studies are needed to determine whether frailty is associated with worsening of CKD and whether intervention to treat frailty can improve physical functioning and health-related quality of life (HRQOL) as well as slow progression of CKD.

Patients undergoing liver transplantation (LT) have a high risk for cardiovascular disease (CVD). Frailty is a frequent condition among LT candidates. Together, CVD and frailty are major causes of morbidity and mortality before and after LT. Conventional methods to diagnose and predict CVD in LT candidates lack sensitivity and clinically relevant application. However, cardiopulmonary exercise testing (CPET) can directly estimate coronary artery disease, cirrhotic cardiomyopathy, and indirectly assess frailty. Such versatility of CPET has caused it to become the standard of care in many LT centers outside of the United States. In preliminary work that will be used to fund a more definitive study (RO1), the investigators plan to investigate CVD and frailty in LT candidates, both from existing standard of care (SOC) methods and CPET. The investigators expect results to improve the current capacity to assess and prognosticate CVD and frailty in LT, ultimately changing practice.

Elderly in residential care spend 97% of their time sedentary. Moreover, exercise therapy often takes place in a poorly stimulating environment which is less motivational for the elderly to undertake regularly. Exercise is however necessary to preserve their physical capabilities and to limit their care dependence. The aim of this study is to investigate the most motivating and stimulating exercise modality for prefrail and frail elderly in nursing homes with which they can reach sufficient training volume. To study this, elderly will exercise in 3 different ways on an ergometer or motomed (according to their physical capabilities): 1) in an environment without other visual stimuli 2) in front of a television with National Geographic images 3) with the interactive software program MemoRide with which participants can exercise in real life on a virtual manner. MemoRide (Activ84Health) uses Google Street View images. The starting point is a connection between an exercise bike and a tablet with a pedalling sensor. This way, pedal frequency is sent to the tablet and as a result, images continue when pedalling. The forth modality is the control modality, in which participants are instructed to rest (supine) during 30 minutes. Based on objective training parameters and metabolic parameters e.g. glucose, insulin, brain-derived neurotrophic factor (BDNF) and lactate, (via a blood sample with a venous catheter) the training modality which offers the best training results will be studied. Secondly, also subject experiences (motivation and emotions) will be evaluated by using questionnaires and observation scales.

This trial studies how well weight bearing exercise works in preventing frailty in stage I-IIIA breast cancer survivors. Weight bearing exercise, including muscle-strengthening, aerobic, flexibility, and balance exercises, can decrease fat and increase muscle, which may lead to reduced frailty.

This study intends to recruit aging population (over 65 years old). The investigators use 16 SrDNA sequencing technology, genome sequencing technology, metabonomics, random forest forecast model, analysing and selecting specific age-related intestinal flora. The investigators select probiotics slowing down senility. Then the investigators use the probiotics to intervene in the aging population. Finally the investigators observe whether the probiotics can delay aging.

The aim of this research project is to evaluate whether olfactory identification impairment is a reliable predictor of preoperative frailty and of postoperative complications and mortality in a population of older patients scheduled for elective surgery. The investigators will measure preoperative olfactory identification function and evaluate whether olfactory impairment predicts frailty, using the Edmonton Frail Scale and handgrip strength. The investigators will analyze whether preoperative olfactory impairment predicts postoperative complications and mortality.

The aim of this study is to evaluate functional and physical capacity, health-related quality of life and associations with frailty in older patients after ischemic heart disease and interventional treatment with an individualized physical training program in the second phase of cardiac rehabilitation.

Research Question: Does the gut microbiome contribute to muscle anabolic resistance to protein supplementation in older adults? Background: Loss of muscle occurs with age and skeletal muscle in older adults can display anabolic resistance to protein in diet. It has been hypothesised that the gut microbiome may play a role in this relationship and therefore could be targeted. Aim: This trial aims to test whether modulation of the gut microbiome, in addition to protein supplementation, can improve skeletal muscle function versus protein supplementation alone. Methods: Double blinded, randomised, placebo controlled, dietary intervention study. Twin pairs will be randomised to either receive protein supplementation plus placebo or protein supplementation plus a gut microbiome modulator (prebiotic plus probiotic) for 12 weeks. Primary outcome will be muscle function measured using chair-rise time. Conclusion: Anabolic resistance warrants further characterisation to guide future therapeutic interventions, especially considering its role in the development of disability, sarcopenia and frailty.

Epidemiological data from Europe have shown that around 30% of subjects aged over 65 years of age are pre-frail, and 15% are frail. Recent research has demonstrated that identifying frailty and implementing preventive measures can help to slow cognitive decline. Screening and treating frailty seem to be a good start towards preventing dependency. On the premise that this frailty is the result of more pronounced tissue alterations in certain elderly subjects, assessment of post-translational modification derived products (PTMDP) represents an innovative evaluation method. These include advanced glycation end-products (AGE), and carbamylation-derived products (homocitrulline). Indeed, the intensity of these modifications increases with ageing, and assessing the products resulting from these alterations could show the existence of differences according to frailty status. This would make it possible to adapt treatment accordingly in elderly subjects.
